TUBE-FRAME SUPPORT.

Application filed October 20,1923. serial 669,868.

To all whom it may concern:

Be it known that LEPPA RYoN, a cit.- izen of the United States, residing at Pasadena, in thecounty of Los Angeles and State of California, have invented anew and use ful Tube-Frame Support, of which the following is a specification.

This invention relates to means for supporting a yarn tube frame in an Axminster carpet or other similar loom. These tube frames provide bearings for the yarn spools and support the numerous yarn tubes through which the pile yarn is presented between the warps of the carpet or other fabno.

It is the general object of my present invention to provide improved devices for supporting a yarn spool on the tube frame and for attaching the tube frame to the transporting pattern chain.

' Particular features of my invention relate to improvements in the construction of the chain engaging hook and to improved means for assembling the support or bracket with the tube frame.

My invention further relates to arrangements and combinations of parts which will be hereinafter described'and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings in which Fig. 1 is a partial front elevation of a tube frame, partly in section and showing my improvements applied thereto;

Fig. 2 is an end elevation of certain parts shown in Fig. 1, and

Fig. 3 is an enlarged detail view to be described.

Referring to the drawings, I have shown a portion of a tube frame of rectangular tubular structure and supporting a large number of yarn tubes 11 through which yarn is delivered from a yarn spool 12. The end bracket or support for the tube frame is shown as formed in two parts 13 and 14, these parts being preferably permanently secured together by welding or in some other convenient manner. I

The part 13 provides a bearing for one end of the yarn spool 12 and the part 14 engages the usual transporting chain (not shown). The part 13 is provided with a laterally projecting portion or arm 15. which extends within the tubular memberlO and is secured thereto by screws .16. The .braclret member or part 14 extends transversely across the end of the tubular member 10 and a projecting end. .portionl'? of the member 10 is bent upwardly :to engage the-end of the part 14 and is secured thereto by screws ment thereof is effectively prevented.

A chain engaging hook is formed with a curved bearing portion 21 and an offset spring-engaging portion 22. y The entire hook is preferably formed from a single rigid piece of material and is secured in the member 10 by a cross pin 23 extending across the tubular member and preferably riveted at its ends therein.

The outer or swinging end of the hook 20 extends upward through slots in the bracket member or part 14, as clearly indicated in Fig. l. A spring 24 is inserted between the lower wall of the member 10 and the under side of theinner portion22 of the book 20. This spring 24 holds the hook 2O yieldingly in the position shown in Fig. 1. For convenience in assembling, the spring 24 is preferably secured to the end portion 22 by a stud v25 (Fig. 3).' When thus constructed, the hook and spring may be assembled before the parts are inserted in the tubular member 10 and thereafter constitute a single unit.

Having thus described my invention, it will be seen that the parts are conveniently manufactured and readily assembled and that a strong, substantial and reliable struc-' ture results from the use of my invention. It will be further evident that changes and modifications can be made therein by those skilled in the art within the spirit and scope of my invention as set forth in the claims and accordingly I do not wish to be otherwise limited to the details herein disclosed, but- What I claim is 1. In a loom, a tubular member, a sup porting bracket comprising a spool-bearing portion having an arm extended at right angles thereto and detachably. secured within said tubular member and having a chainengaging portion fixed to said spool-supporting portion, extending transversely across the end of said tubular member, and abuttion, and a bearing stud for said hook fixed ting the ends of the side walls thereof, and said tubular member having an end portion bent around the lower end of said chainengaging vportion of said bracket to engage the outer face thereof, and means to detachin the walls of said tubular member.

.3. In a loom, a tubular member, a supporting bracket attached thereto, a rigid hook extending freely through an opennig in said bracket and supported independently of said bracket, said hook having a pivotal bearing portion within said tubular member and having an offset end projection, means fixed in said tubular member to pivotally support said hook, and a spring permanently secured to said end projection and engagingv an inner wall of said tubular member to hold said hook yieldingly in operative position.

4:. As an article of manufacture, a rigid chain-engaging hook adapted for use in a hollow tube frame having an open end, said hook having a curved portion forming an open bearing and having a laterally project:

ing end portion, a coil spring to move said hook, and means to permanently secure said spring to the projecting end portion of said hook to be handled as a unit therewith. In testimony whereof I- have hereunto affixed my signature.
